IMPRQVEMENTIN FLouR-BOLTING REELS.

Specificationforming part of Letters Patent No. 116,331, dated May 30,1,871.

Be it known that LFLTCH B. LEWIS, of Tifin, in the county of Seneca andState of Ohio, have invented certain Improvements in Bolting-Reels; andI do hereby declare that u the following is a full, clear, and exactdescription thereof, reference being had' to the accompanying drawingmaking part .of this specification, in which- Figure 1, `Plate l, is atop view ofthe reel las seen" by removingthe upper half of thereel-chest. Fig. 2, Plate 1, is a view of two hammers and theiractuating mechanism,

showing the hammers raised from their anvils ready to strike. Fig. 3,Plate 2, is a cross- `section of the boltin g-chest and the reel. Fig.

4, Plate 2, is a perspective view of a hammer and its rod. Fig. 5, Plate2,is a perspective view, showing the Wedge-cam, and also an antifrictionroller on one of the actuating-rods.

Similar letters of reference indicate corresponding parts in the severalfigures. This invention relates to improvements on mechanism foroperating hammers or knockers upon a bolting-reel for the purpose ofjarring the reel during the operation of bolting flour. The nature of myinvention consists, first, in crankin g each hammer-handle insuch mannerthat the handle serves as a pivot for the hammer, and also a meanswhereby the hammer can be operated `by a rod having an4 endwise motion,as will be hereinafter explained; second, the anvil-bed, constructedarranged inside of the reel, at one end thereof, as to be capable ofadjustment for regulating the force of the blows of the hammer upon utheir anvils; fourth in providing each actuating-rod with ananu-friction roller and applying this roller to a detachable socket, aswill be hereinafter explained. y i

To enable others skilled in the art to understand my invention, I willexplain its construc- In the accompanying drawing, A represents abolting-chest, withinwhich a reel is arranged to rotate freely. Thisreel may be constructed Vin the usual well-known manner. It consists ofacentral shaft, B, from which arms C -0 otal portion, b2.

radiate, which have attached to them the reel bars or ribs D D, six,more or less, in number. G G are the hammer-actuating rods, two of whichare represented in the drawing, arranged on opposite sides of the reeland parallel to the reel-shaft B. As the hammer mechanism is preciselyalike on both sides of the shaft B, I will, for simplicity ofdescription, refer to the mechanism on one side of this shaft. The rod Gextends nearly the whole length of the reel, andnear one end it passesthrough an arm, g, and is guided by said arm. That end of the rod Gnearest this arm has a socketbearing, r, securedon it by means of asetscrew, V; and to the end of this socket-bearing an anti-frictionroller, p, is applied, which rolls against the surface of a cam-segment,L.` By thus applying the roller to a'removable piece, r, it will be seenthat when the pulley wears out its place can be readily supplied Withoutdetachin g the rod G. The cam L, whichk gives endwise motion to the rodG, is a beveled segment, which is hung inside ofthechest A, at one endthereof, and which can be adjusted for giving more or less throw to saidrod by means of a rope or chain, m. VThis segment L is pivoted at t, sothat it can be adjusted Within the range of the pulley p onrod G, as thepulley revolves with the reel. The drawing shows the rope m attacheddirectly to the segmentL; but a modication of this plan would be toapply an arm to the back of thesegment and attach the rope to the end ofthis arm. To the reel-rib D, inside thereof, I securenarrowanvil-beds JJ, each one of which has an anvil, j, formed on one end, and aneyebearing, t', formed on the other end. To e'ach bed J a hammer ispivoted in the following manner: a represents the hammer-head, and b itshandle. The handle is bent at three points, x m x, V(see Fig. 4,) insuch manner as to form the pivotal part h3, which is received by the`eye-bearing i; also a crank-arm, b1, and a piv- The arm portion extendsfrom the eye-bearing t' to the inner end of van attaching-block, c,Which is made fast to the rod G by a set-screw, s. Thus it will be seenthat each hammer is attached to the anvil-bed J and to a block, c, onthe actuating-rod G, by means of a single rod, which is bent so as toform the pivotal connections and the crankarm. The hammers are held downupon their anvils by means of a spring, S, applied as clearly shown inFigs. l and 2.

Having described my invention, I claim- 1. The hammer-handle, cranked atx a: so as to form the pivotal portions b3 b2, and the crank-arm b1, incombination with the eyebearing z' and the attaching-block c, and theendwise movable rod G, substantially as described. 2. The combination,with the bolt-bar D, of the rod G, anvil J provided with raised p0rtionj and eye i, hammer a having crank-handle b b1 b2l and actuated byspring S, when constructed, arranged, and operating as shown anddescribed, for the purpose set forth.
